VI. SUMMARY OF CONTRIBUTIONS AND FUTURE WORK
6.5. Future Work
6.5.1. Visual interest and view clarity
Previous studies that examined perceptual responses to fractal patterns were mainly conducted in windowless rooms, including the first two studies in this dissertation. The
provision of view and daylight in the room might present competing factors that might influence visual interest. Specifically, a view of nature through windows might reduce the relative
significance of computer-generated fractals. Thus, future studies should examine whether the visual interest of projected light patterns is influenced by the presence of these two variables. Another research area that warrants further exploration is related to investigating view clarity through different patterns. It is hypothesized that the adequacy of window patterns for improving view clarity depends on the relationship between view type and pattern geometry. For instance, it might be possible that fractal patterns reduce visibility the most while looking at a scene of nature. The results of such efforts can help inform the selection of window patterns to improve visual interest and view quality.
6.5.2. Visual interest of sunlight patterns
In studies 3 and 4, view quality was consistently higher for the clear condition, therefore, to isolate the effects of views, future studies should examine visual comfort and visual interest of sunlight patterns when parallel to the window without access to outdoor
101
views. This would help determine whether sunlight pattern geometry can be potentially used to enhance visual interest and visual comfort in windowless rooms.
Future studies should examine tradeoffs and interactions between views, visual interest of sunlight patterns, and visual comfort to examine whether the visual interest of sunlight patterns increases tolerance to glare as suggested by previous studies (Tuaycharoen & Tregenza, 2005). Further, to explore the extent to which outdoor view is maintained despite glare. These research areas can be investigated by examining occupant’s behavioral responses, e.g. shade control, under different sunlight conditions.
